curl或file_get_contents不起作用

Question

当我发送帖子请求时，有一些问题。 我用这个脚本执行页面http://localname.local/test，页面http://localname.local/directory/page.php得到一个json数据。

$url = "http://localname.local/directory/page.php"; 

$post = [ 
    "key1" => "hello", 
    "key2" => 885, 
]; 

$options = array(
    'http' => array(
     'header' => "Content-type: application/x-www-form-urlencoded\r\n", 
     'method' => 'POST', 
     'content' => http_build_query($post), 
     'timeout' => 10 
    ) 
); 
$context = stream_context_create($options); 
$result = file_get_contents($url, false, $context); 


if ($result === false) { 
    // Handle error 
    return null; 
} 
else 
    return $result; 

但经过10个secondes，剧本得到的消息：

Warning: file_get_contents(http://localname.local/directory/page.php): failed to open stream: HTTP request failed! in D:\ ... \html\test.php on line X

的page.php文件作品，我可以送岗位要求与我的浏览器作为客户端，但PHP（或WAMP）可以”访问或发送请求到自己的页面。

我得到了PHP 7.1.7，Apache 2.4.23在wam 3.0.9上，选项allow_url_fopen打开。

编辑： 为卷曲

public static function get_content($post) 
{ 
    $url = "http://localname.local/directory/page.php"; 

    $query = http_build_query($post); 
    $curl = curl_init(); 
    curl_setopt($curl, CURLOPT_URL, $url); 
    curl_setopt($curl, CURLOPT_POST, true); 
    curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10); // Tell cURL that it should only spend X seconds trying to connect to the URL in question. 
    curl_setopt($curl, CURLOPT_TIMEOUT, 10); // A given cURL operation should only take X seconds max. 
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // returns data to function 
    curl_setopt($curl, CURLOPT_POSTFIELDS, $query); 
    $data = curl_exec($curl); 

    if (curl_errno($curl)) 
     throw new Exception(curl_error($curl)); 

    curl_close($curl); 

    return $data; 
} 

得到

Fatal error: Uncaught Exception: Operation timed out after 10000 milliseconds with 0 bytes received in D:\ ... \html\test.php on line X

Exception: Operation timed out after 10000 milliseconds with 0 bytes received

Answer 1

真正的问题

1. test.php使用session_start()
2. test.php推出的page.php
3. page.php一个POST request使用session_start()< < <冻结

我们不能用2届PHP在同一时间。会话锁定并创建无限循环。

谢谢大家帮我找到解决方案。

对于file_get_contents（）函数打开网址，您必须启用php.ini文件中设置allow_url_fopen。

安全明智的我劝你实现你与cURL做什么：

function get_content($url,$post){ 
    $query = http_build_query($post); 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL, $URL); 
    curl_setopt($ch, CURLOPT_POST, true); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); // returns data to function 
    curl_setopt($ch, CURLOPT_POSTFIELDS,$query); 
    $data = curl_exec($ch); 
    // if you want to display error messages, do it before curl_close() 
    //echo curl_errno($ch); // if you want to display error number 
    //echo curl_error($ch); // if you want to display error message 
    curl_close($ch); 
    return $data; 
} 

echo get_content('http://localname.local/directory/page.php');

我认为你需要增加CURLOPT_TIMEOUT时间
